Athletics at Boston Red Sox: Polymarket's Two-Minute Reprice

Across the Athletics at Boston Red Sox fixture on August 7, Polymarket moved Boston Red Sox from 75.5% to 90.5% in a two-minute window ending at 23:43 UTC. Eight minutes after that reading, BetMGM was recorded with the same side at 95.1%. Nine venues carried the fixture.

Two minutes is what separates this from ordinary drift. A reprice of this size developing over a session is one kind of market event. The same move compressed into two minutes is another, and the distinction only becomes visible when the window is pinned. The recording establishes the pace and the sequence: Polymarket reached 90.5% at 23:43 UTC, and BetMGM was at 95.1% when recorded eight minutes later. A price alone tells you where a market landed. The window tells you how fast it moved to get there.
